Investments, Debt and Equity Securities [Abstract] |
Residential Mortgage Securities and MSR-Related Assets | Residential Mortgage Securities and MSR-Related Assets Agency and Non-Agency MBS MBS investments held as of June 30, 2020 or in prior periods include Agency MBS and Non-Agency MBS which include MBS issued prior to 2008 (“Legacy Non-Agency MBS”). These MBS are secured by: (i) hybrid mortgages (“Hybrids”), which have interest rates that are fixed for a specified period of time and, thereafter, generally adjust annually to an increment over a specified interest rate index; (ii) adjustable-rate mortgages (“ARMs”), which have interest rates that reset annually or more frequently (collectively, “ARM-MBS”); and (iii) 15 and 30 year fixed-rate mortgages for Agency MBS and, for Non-Agency MBS, 30-year and longer-term fixed rate mortgages. In addition, the Company’s MBS are also comprised of MBS backed by securitized re-performing/non-performing loans (“RPL/NPL MBS”), where the cash flows of the bond may not reflect the contractual cash flows of the underlying collateral. The Company’s RPL/NPL MBS are generally structured with a contractual coupon step-up feature where the coupon increases from 300 - 400 basis points at 36 - 48 months from issuance or sooner. The Company pledges a significant portion of its MBS as collateral against its borrowings under repurchase agreements and Swaps (see Note 7). Agency MBS: Agency MBS are guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as Ginnie Mae. The payment of principal and/or interest on Ginnie Mae MBS is explicitly backed by the full faith and credit of the U.S. Government. Since the third quarter of 2008, Fannie Mae and Freddie Mac have been under the conservatorship of the Federal Housing Finance Agency, which significantly strengthened the backing for these government-sponsored entities. The Company sold its remaining holdings of Agency MBS during the quarter. Non-Agency MBS: The Company’s Non-Agency MBS are primarily secured by pools of residential mortgages, which are not guaranteed by an agency of the U.S. Government or any federally chartered corporation. Credit risk associated with Non-Agency MBS is regularly assessed as new information regarding the underlying collateral becomes available and based on updated estimates of cash flows generated by the underlying collateral. As of June 30, 2020, the Company has sold substantially all of its holdings of Legacy Non-Agency MBS and substantially reduced its holdings of other Non-Agency MBS. CRT Securities CRT securities are debt obligations issued by or sponsored by Fannie Mae and Freddie Mac. The coupon payments on CRT securities are paid by the issuer and the principal payments received are dependent on the performance of loans in either a reference pool or an actual pool of loans. As an investor in a CRT security, the Company may incur a principal loss if the performance of the actual or reference pool loans results in either an actual or calculated loss that exceeds the credit enhancement of the security owned by the Company. The Company assesses the credit risk associated with its investments in CRT securities by assessing the current and expected future performance of the associated loan pool. The Company pledges a portion of its CRT securities as collateral against its borrowings under repurchase agreements (see Note 7). The following tables present certain information about the Company’s residential mortgage securities at June 30, 2020 and December 31, 2019: June 30, 2020

During the three months ended March 31, 2020, the Company recognized an impairment loss related to its Non-Agency MBS of $63.5 million based on its intent to sell, or the likelihood it will be required to sell, its remaining securities. Gross unrealized losses on the Company’s Non-Agency MBS were $6.4 million at June 30, 2020. Based upon the most recent evaluation, the Company does not consider these unrealized losses to require an allowance for credit losses and does not believe that these unrealized losses are credit related, but are rather a reflection of current market yields and/or marketplace bid-ask spreads. The Company has reviewed its Non-Agency MBS that are in an unrealized loss position to identify those securities that require an allowance for credit losses based on an assessment of changes in expected cash flows for such securities, which considers recent bond performance and, where possible, expected future performance of the underlying collateral. The Company did not recognize an allowance for credit losses (or other than temporary impairment in prior year periods) through earnings related to its Non-Agency MBS during the three and six months ended June 30, 2020 and 2019. The following table presents a roll-forward of the allowance for credit losses on the Company’s Residential mortgage securities and MSR-related assets:

MSR-Related Assets (a) Term Notes Backed by MSR-Related Collateral At June 30, 2020 and December 31, 2019, the Company had $224.8 million and $1.2 billion, respectively, of term notes issued by SPVs that have acquired rights to receive cash flows representing the servicing fees and/or excess servicing spread associated with certain MSRs. Payment of principal and interest on these term notes is considered to be largely dependent on cash flows generated by the underlying MSRs, as this impacts the cash flows available to the SPV that issued the term notes. At June 30, 2020, these term notes had an amortized cost of $184.3 million, gross unrealized gains of $40.5 million, a weighted average yield of 12.87% and a weighted average term to maturity of 9.7 years. During the three and six months ended June 30, 2020, the Company sold certain term notes for $574.9 million and $711.7 million, realizing gains of $53.3 million and $28.7 million, respectively. During the three months ended March 31, 2020, the Company recognized an impairment loss related to its term notes of $280.8 million based on its intent to sell, or the likelihood it will be required to sell, such notes. At December 31, 2019, the term notes had an amortized cost of $1.2 billion, gross unrealized gains of $5.2 million, a weighted average yield of 4.75% and a weighted average term to maturity of 5.3 years. (b) Corporate Loans The Company has made or participated in loans to provide financing to entities that originate residential mortgage loans and own the related MSRs. These corporate loans are secured by MSRs, as well as certain other unencumbered assets owned by the borrower. During the year ended December 31, 2018, the Company participated in a loan where the Company committed to lend $100.0 million of which approximately $31.8 million was drawn at June 30, 2020. At June 30, 2020, the coupon paid by the borrower on the drawn amount is 5.26%, the remaining term associated with the loan is 2 months and the remaining commitment period on any undrawn amount is 2 months. During the remaining commitment period, the Company receives a commitment fee between 0.25% and 1.0% based on the undrawn amount of the loan. The borrower has an option to extend the term of the loan and the commitment period for an additional twelve months.

(1) Includes amortization of premium paid net of accretion of purchase discount. For Agency MBS, RPL/NPL MBS and the corporate loan secured by MSRs, interest income is recorded at an effective yield, which reflects net premium amortization/accretion based on actual prepayment activity. (2) The effective yield adjustment is the difference between the net income calculated using the net yield less the current coupon yield. The net yield may be based on management’s estimates of the amount and timing of future cash flows or on the instrument’s contractual cash flows, depending on the relevant accounting standard. (3) Includes accretion income recognized due to the impact of redemptions of certain securities that had been previously purchased at a discount of approximately $277,000 and $148,000 during the six months ended June 30, 2020 and 2019, respectively.
